Before I mention any tips or suggestions for how to more effectively teach data science, I want to start by saying that teaching data science is not an easy task. With so many application domains and encompassing subdomains, no one class or series of classes can ever hope to cover the world of data science. Additionally, I want to highlight that everything here is simply my view of the data science world — a world I have studied, but only recently been emersed in.
With that being said, I still believe there are a number of useful suggestions that can help supplement student learning in the classroom when it comes to data science. As I transition from classroom learning to the business world, I can’t help but notice the disconnect between the two and how this gap could be mitigated. Below are 10 tips that I believe will not only further enhance the data science learning experience, but also help to prepare individuals for careers in data science.
One of the first things you learn in computer science is that variables should be appropriately and succinctly named. A name too long is inefficient to type and makes code clunky. A name too short may not be representative enough of the variable’s contents. There seems to be some sort of middle ground sweet spot, but how do you find it. My advice for the best naming practice is to create the shortest name possible, such that a person other than yourself (with limited to no knowledge of the code or project) can accurately tell what the variable represents.
While the worst examples of poor naming can cause the developer themselves to forget what a variable represents, most times disobeying the rules of the name game will make things confusing for others. Poor variable assignment effects can also be seen outside the environment of one’s code too. Databases often contain a plethora of examples of poor attribute naming, containing unexplained acronyms, excessive_use_of_underscores, etc. Sometimes these tactics are necessary, as variables can represent rather complex ideas and figures. However, when these practices are utilized, it is important to document these areas of confusion, so that future users or editors of the code/database (including yourself), will not be lost.
Variable assignment is only one potential source of confusion when coding or developing a data science project. Due to the fact that certain code blocks can become rather convoluted, commenting is usually seen as a way to explain some of the intricacies. However, oftentimes comments are randomly strewn throughout code here and there and used as short term reminders for the developer, rather than designed for users or other editors of the code later on. Having readable and clean code is arguably just as important as having code that will run smoothly and therefore should be highly stressed to students. The way I see it, the more one explains what is happening within their code, the longer they can expect that code to be used in practice. If only you yourself can understand how it works then it is more likely to die once you commence working on it.

If you accumulate data on which you base your decision-making as an organization, you should probably think about your data architecture and possible best practices.
If you accumulate data on which you base your decision-making as an organization, you most probably need to think about your data architecture and consider possible best practices. Gaining a competitive edge, remaining customer-centric to the greatest extent possible, and streamlining processes to get on-the-button outcomes can all be traced back to an organization’s capacity to build a future-ready data architecture.
In what follows, we offer a short overview of the overarching capabilities of data architecture. These include user-centricity, elasticity, robustness, and the capacity to ensure the seamless flow of data at all times. Added to these are automation enablement, plus security and data governance considerations. These points from our checklist for what we perceive to be an anticipatory analytics ecosystem.

The buzz around data science has sent many youngsters and professionals on an upskill/reskilling spree. Prof. Raghunathan Rengasamy, the acting head of Robert Bosch Centre for Data Science and AI, IIT Madras, believes data science knowledge will soon become a necessity.
IIT Madras has been one of India’s prestigious universities offering numerous courses in data science, machine learning, and artificial intelligence in partnership with many edtech startups. For this week’s data science career interview, Analytics India Magazine spoke to Prof. Rengasamy to understand his views on the data science education market.
With more than 15 years of experience, Prof. Rengasamy is currently heading RBCDSAI-IIT Madras and teaching at the department of chemical engineering. He has co-authored a series of review articles on condition monitoring and fault detection and diagnosis. He has also been the recipient of the Young Engineer Award for the year 2000 by the Indian National Academy of Engineering (INAE) for outstanding engineers under the age of 32.
Of late, Rengaswamy has been working on engineering applications of artificial intelligence and computational microfluidics. His research work has also led to the formation of a startup, SysEng LLC, in the US, funded through an NSF STTR grant.

Data Science becomes an important part of today industry. It use for transforming business data into assets that help organizations improve revenue, seize business opportunities, improve customer experience, reduce costs, and more. Data science became the trending course to learn in the industries these days.
Its popularity has grown over the years, and companies have started implementing data science techniques to grow their business and increase customer satisfaction. In online Data science course you learn how Data Science deals with vast volumes of data using modern tools and techniques to find unseen patterns, derive meaningful information, and make business decisions.
Advantages of Data Science:- In today’s world, data is being generated at an alarming rate in all time lots of data is generated; from the users of social networking site, or from the calls that one makes, or the data which is being generated from different business. Because of that reason the huge amount of data the value of the field of Data Science has many advantages.
